Nuclear Engineering Services (NES) has completed installation of flask leak test equipment (FLTE) at the Dounreay fast reactor facility in Scotland.

The contract has been delivered for Dounreay Site Restoration, a wholly-owned subsidiary of the Babcock Dounreay Partnership, a consortium of Babcock International Group, CH2MHILL and URS.

NES project manager Chris Childs said "The scope of supply demonstrates NES’ full capabilities, taking a requirement to improve a process by two of our customers, engineering and demonstrating a viable solution, and following it with the manufacture and installation of the units at our customer’s sites."

The installation marks the last of the series of contracts, which included setting up 19 FLTE units across 13 sites.

NES said it has also been supplied the FLTE equipment to both EDF AGR and Magnox sites across the country.

The FLTE was initially developed in 2004 as a prototype unit in a joint venture for both EDF and Magnox, to confirm that flasks containing spent nuclear fuel are fully sealed prior to their transportation to Sellafield for fuel reprocessing.
